{"version":"1.0","type":"rich","title":"activity","description":"This example demonstrates a minimal \"Hello VizHub!\" message centered on the page with D3.js styling. It shows how to load D3 via UNPKG, import functions such as `select` from the `d3` module, and import a local ES6 module (`myMessage.js`) to supply the text content. The code uses `d3.select` to target the `#message` div and set its text, with CSS controlling the large centered font size. No data source or complex rendering is involved.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9dca41319cd14d14b68d124b8920bf95?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
